As the reputed world leader in green energy policy, Germany plans to eliminate nuclear power as an energy source in the next 5 years.

A 2011 decision to phase out nuclear power by 2022 has meant that renewables like wind and solar power are expected to swiftly take the place of nuclear energy on the German power grid. The portion of Germany’s power generation from wind and solar (renewables) has indeed risen dramatically in the last 10 years:

Germany’s “green” leadership and vociferous allegiance to renewables as a dominant power generation source has elicited controversy. Wind and solar are very labor and material-intensive (expensive) energy sources, and the dramatic rise in solar and wind power capacity has come with great financial expense to German citizens. Poorer households have long been the most adversely affected. Dating back to 2000, electricity prices have risen by 80% in Germany, leaving 7 million citizens “energy poor” (meaning that more than 10% of their income has to be spent on heating and electrifying their homes).

Analysis by the European Commission indicates that “nearly 11% of the EU’s population [encompassing 54 million people] are in a situation where they live in households in which they find themselves unable to heat their homes at an affordable cost,” which may effectively put their lives at risk. This latter point is not an exaggeration. In the UK, where heating costs rose 63% between 2009 and 2014, 25% of citizens over 60 are classified as “energy poor”, leaving the elderly population especially vulnerable. During the frigid winter of 2014, the number of “excess winter deaths” reached 49,260, of which about 14,780 were due to people living in cold homes that they couldn’t afford to heat.

And despite the steep, expensive rise in power generated by renewables since about 2000, Germany still obtained about 44% of its power from coal as of 2014, which is a higher share than in the United States (33% as of 2015). Hundreds of U.S. coal plants have been shuttered in recent years largely because of a monumental nation-wide shift to natural gas power generation, a cleaner fuel that emits much less CO2 upon combustion than does coal.

(In the U.S., in fact, there has been a 12% decline in overall CO2 emissions since 2005 despite the fact that the U.S population has risen by 30 million during those 10 years. As mentioned above, much of the decline in emissions is directly connected to the rapid displacement of coal with natural gas power generation. While the rise in U.S. solar power has also been substantial in the last decade, “for every ton of carbon dioxide cut by solar power, hydraulic fracturing for natural gas cut 13 tons.”)

Germany’s heavy reliance on coal — the highest in the EU — is very likely to continue indefinitely despite the nation’s stated commitments to the Paris Agreement and CO2 emissions reductions. The much lower power-generating capabilities of renewables due to their intermittent output (the Sun has to shine and the wind must blow) has meant that reliable backup capacity — fossil fuels or nuclear — must remain on the grid. Since nuclear power is set to be phased out of Germany by 2022, coal necessarily has to stay, even expand. The natural consequence is that Germany’s CO2 emissions have not declined since 2009, and instead there has been a slight emissions uptick in recent years, as the dramatic increase in renewables has not come close to offsetting the greater CO2 emissions generated from the renewed German emphasis on coal.

Adding More Wind And Solar Power Ultimately Raises CO2 Emissions, As More Fossil Fuel Backup Capacity Must Be Built

What’s happening in Germany is, unfortunately, a bellwether for what is to come in other large wealthy countries attempting to make renewables the kingpin of their power grids. The unspoken truth about renewables was succinctly summarized in a 2012 Los Angeles Times analysis :

“As more solar and wind generators come online, … the demand will rise for more backup power from fossil fuel plants.”

Wind provided just 33 megawatts of power statewide in the midafternoon, less than 1% of the potential from wind farms capable of producing 4,000 megawatts of electricity.

As is true on many days in California when multibillion-dollar investments in wind and solar energy plants are thwarted by the weather, the void was filled by gas-fired plants like the Delta Energy Center.

One of the hidden costs of solar and wind power — and a problem the state is not yet prepared to meet — is that wind and solar energy must be backed up by other sources, typically gas-fired generators. As more solar and wind energy generators come online, fulfilling a legal mandate to produce one-third of California’s electricity by 2020, the demand will rise for more backup power from fossil fuel plants.

Another observational analysis suggests that much of the power generation thought to be attributed to wind actually came from backup sources, or fossil fuels:

“More than half the electric generation nominally credited to wind power is actually produced by fossil fuels, mostly natural gas.”

Analysis from a recently published resource management paper suggests that overall CO2 emissions will actually double in the next 16 years (by 2032) in Canada (Ontario) as more wind and solar capacity is added. Wind and solar require reliable backup when the Sun isn’t shining and/or the wind isn’t blowing…and fossil fuel energies (natural gas, coal) are the reliable backup(s) of choice.

Wind and Solar require flexible backup generation. Nuclear is too inflexible to backup renewables without expensive engineering changes to the reactors. Flexible electric storage is too expensive at the moment. Consequently natural gas provides the backup for wind and solar in North America. When you add wind and solar you are actually forced to reduce nuclear generation to make room for more natural gas generation to provide flexible backup.

Ontario currently produces electricity at less than 40 grams of CO2 emissions/kWh. Wind and solar with natural gas backup produces electricity at about 200 grams of CO2 emissions/kWh. Therefore adding wind and solar to Ontario’s grid drives CO2 emissions higher.

From 2016 to 2032 as Ontario phases out nuclear capacity to make room for wind and solar, CO2 emissions will double (2013 LTEP data). In Ontario, with limited economic hydro and expensive storage, it is mathematically impossible to achieve low CO2 emissions at reasonable electricity prices without nuclear generation.

Scientists Increasingly Conclude Global-Scale Renewables-Driven Power Supply Will Never Happen

Scientists have increasingly weighed in on the vacuousness of the current emphasis on renewable energy generation. For example…

—

Solar power is a “non-sustainable energy sink” and “will not help in any way to replace the fossil fuel” even though “many people believe renewable energy sources to be capable of substituting fossil or nuclear energy.”

As well as the extra fossil fuel based energy plants required to backup wind and solar installations, keep in mind the additional CO2 produced and mining required to manufacture, transport and maintain windmills and solar panels.

With an average lifespan of only fifteen years, running at max 30% output, an industrial windmill could spin until it falls apart and never generate as much energy as was invested in building it.

Because wind power fails when the wind stops blowing, 100% of its capacity has to be backed up 100% of the time by fossil fuels which run constantly in the background to balance the grid and prevent blackouts when wind power output collapses:

The energy required for a helicopter to de-ice all the blades on a wind farm must outweigh any supposed saving in CO2 by a factor of 100 or more. Notwithstanding that no wind farm has saved a gram of CO2 due to construction and the necessary spinning reserve.

Surely the blades are made from aluminium? Spell check is trying to make me spell it, “aluminum”…WTF? Is that the American way to spell it?
Anyway, the manufacture of aluminium uses vast amounts of power. Much more than steel.
